Land subsidence is the gradual or abrupt sinking of the Earth's surface caused by the migration of earth elements underground.

Aquifer-system compaction, drainage of organic soils, underground mining, hydro compaction, natural compaction, sinkholes, are the main causes of land subsidence. The loss of levee freeboard and subsequent reduction in flood protection, the change in gradient along water conveyance canals, damage to roads and bridges, and the collapse of water well casings are some major consequences of land. When a lot of groundwater has been taken out of particular kinds of rocks, like fine-grained sediments happens. The ground is held up in part by the water, which causes the rock to compact. The rocks collapse in on themselves when the water is turned off.

The effective stress at 5 m depth would be 75.38 kPa

Effective stress is the stress that is transmitted between soil particles, and is important for calculating the amount of skin friction developed along the length of driven piles. To calculate the effective stress at a depth of 5 m, we need to consider the weight of the soil above the depth of interest and the weight of the water above the soil. For low tide conditions, the water level is 2 m below the ground surface, so the effective stress at 5 m depth would be the unit weight of the sand multiplied by the depth of soil above it, which is 5 m. Thus, the effective stress at 5 m depth would be 95 kPa (19 kN/\(m^3\)x 5 m).

For high tide conditions, the water level is 2 m above the ground surface, so we need to consider the weight of the water as well. The weight of the water above the 5 m depth of soil is (2 m x 9.81 kN/\(m^3\)), which is 19.62 kN/\(m^2\). Therefore, the effective stress at 5 m depth would be the unit weight of the sand multiplied by the depth of soil above it (5 m) minus the weight of the water above it (19.62 kN/\(m^2\)). Thus, the effective stress at 5 m depth would be 75.38 kPa (19 kN/\(m^3\) x 5 m - 19.62 kN/\(m^2\)).

Probability that bulb is defective :

Let :

b1 = box 1 ; b2 = box 2 ; b3 = box 3

d = defective

P(defective bulb) = (p(b1) * (d|b1)) + (p(b2) * p(d|b2)) + (p(b3) * p(d|b3))

P(defective bulb) = (1/3 * 10/20) + (1/3 * 7/15) + (1/3 * 5/10))

P(defective bulb) = 10/60 + 7/45 + 5/30

P(defective bulb) = 1/6 + 7/45 + 1/6 = 0.4888

= 0.49

P(bulb is good) = 1 - P(defective bulb) = 1 - 0.49 = 0.51

The weak electrical attractions within polypeptide chains account for the protein's secondary structure.

The secondary structure of a protein is formed by weak electrical attractions within polypeptide chains. These weak attractions primarily include hydrogen bonds between the amino acid residues in the protein sequence. The secondary structure refers to the regular, repetitive patterns that arise from these hydrogen bonding interactions. The two most common secondary structures in proteins are alpha helices and beta sheets.

In an alpha helix, the polypeptide chain forms a spiral shape held together by hydrogen bonds between the amino acid residues. In beta sheets, the polypeptide chain folds back and forth, forming a sheet-like structure stabilized by hydrogen bonds between adjacent chains. The primary structure of a protein refers to the linear sequence of amino acids, while the tertiary structure involves the overall three-dimensional folding of a single polypeptide chain.

The quaternary structure refers to the arrangement of multiple polypeptide chains in a protein complex. Therefore, it is the weak electrical attractions within polypeptide chains that specifically contribute to the formation of the protein's secondary structure.

The "Airport" class in Java is designed to represent an airport with fields such as identifiers, coordinates (latitude and longitude), magnetic variation, and elevation above sea level.

The class includes accessor and mutator methods for each field to retrieve and modify their values. The convention is that negative longitude indicates the airport is located west of the Greenwich Meridian, and negative latitude indicates it is south of the equator.

The "Airport" class in Java encapsulates the essential information related to an airport. It includes fields such as the identifier (e.g., airport code), coordinates (latitude and longitude), magnetic variation (indicating the magnetic deviation from true north), and elevation above sea level. The class provides accessor methods, also known as getter methods, to retrieve the values of these fields, and mutator methods, also known as setter methods, to modify the field values.

In this specific implementation, when the longitude value is negative, it signifies that the airport is located west of the Greenwich Meridian. Similarly, a negative latitude value indicates that the airport is situated south of the equator. By following this convention, it becomes easier to determine the location of an airport based on its coordinates.

Using the "Airport" class, one can create instances representing different airports by setting values for their respective fields. These instances can then be utilized in various applications related to airport management, navigation systems, or geographical data analysis. The accessor and mutator methods provide a means to access and modify the airport information, ensuring encapsulation and data integrity within the class.

Technician A and Technician B both are correct as brake fluid that is allowed to remain uncovered does absorb water and brake fluid can damage the paint on a vehicle's fender if it is accidentally spilled.

Technician A is correct because brake fluid is hygroscopic, which means it absorbs moisture from the atmosphere. This water can corrode brake parts and lead to failure, as well as increase the fluid's boiling point, leading to brake fade and reduced stopping power.
Technician B is also correct because brake fluid is made up of corrosive materials that can break down paint and other surfaces. If the brake fluid is not cleaned off the fender immediately, it can cause permanent damage to the paint.

Answer: (d−4) 2

Explanation: Factoring  d2-8d+16

The first term is,  d2  its coefficient is  1 .

The middle term is,  -8d  its coefficient is  -8 .

The last term, "the constant", is  +16

Step-1 : Multiply the coefficient of the first term by the constant   1 • 16 = 16

Step-2 : Find two factors of  16  whose sum equals the coefficient of the middle term, which is   -8 .

     -16    +    -1    =    -17

     -8    +    -2    =    -10

     -4    +    -4    =    -8    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  -4

                    d2 - 4d - 4d - 16

Step-4 : Add up the first 2 terms, pulling out like factors :

                   d • (d-4)

             Add up the last 2 terms, pulling out common factors :

                   4 • (d-4)

Step-5 : Add up the four terms of step 4 :

                   (d-4)  •  (d-4)

            Which is the desired factorization

  Multiply  (d-4)  by  (d-4)

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is  (d-4)  and the exponents are :

         1 , as  (d-4)  is the same number as  (d-4)1

and   1 , as  (d-4)  is the same number as  (d-4)1

The product is therefore,  (d-4)(1+1) = (d-4)2

Because it helps to speed up recovery and required recovery efficiency When recovering refrigerant from a household refrigerator who's compressor does not run

The maximum shear stress is  R = 25 MPa

Since the Von Mises stress in this case is less than the yield stress

From the circle, we can read off the principal stresses  as the two intersections of the circle with the horizontal axis. In this case, the principal stresses are:

σ1 = σavg + R = 35 MPa

σ2 = σavg - R = -15 MPa

The maximum shear stress is given by the radius of the circle, which is equal to half of the difference between the two principal stresses:

τmax = R = 25 MPa

In order to determine if the plate will yield under uniaxial tension with a yield stress of 80 N/mm², we first need to convert the units of the stress values we obtained earlier from MPa to N/mm²:

σ1 = 35 MPa = 35 N/mm²

σ2 = -15 MPa = -15 N/mm²

Substituting these values into the Von Mises yield criterion equation, we get:

σVM = √(35² - 35(-15) + (-15)²) = 51.96 N/mm²

Since the Von Mises stress in this case is less than the yield stress
